Mark Gordon and Constance Marten have both been found guilty of gross negligence manslaughter.

Marten, 38, and Gordon, 51, both denied the charges at the Old Bailey following the death of their child, Victoria.

Victoria died in a tent in the South Downs in January 2023, with her body recovered two months later.

There had been a high-profile police search for the missing baby, which culminated in the couple’s arrests in Brighton in February 2023 after 54 days on the run across England.

The couple left home with their young daughter after their four other children were taken into care.

Constance Marten, who is from a wealthy family, and her convicted rapist partner disposed of the baby's body in a Lidl shopping bag in Brighton.

Victoria’s remains were too badly decomposed to establish the cause of death.

She likely died from hypothermia in the cold and damp conditions or was smothered, the prosecution said.

The re-trial came after the defendants were convicted of perverting the course of justice, concealing the birth of a child and child cruelty in their first trial last year.

Detective Superintendent Lewis Basford of Scotland Yard, said: “Today, the justice we have long fought for has been finally been served for baby Victoria.

“The selfish actions of Mark Gordon and Constance Marten resulted in the death of a newborn baby who should have had the rest of her life ahead of her.”

Victoria's death was described as "completely avoidable" by Basford, who said the defendant had plenty of opportunities to "do the right thing" and ask for help.
